Description

L'invention est relative à un bouchon à vis comportant une bague d'inviolabilité se rompant lors de la première ouverture du récipient sur lequel le bouchon est monté pour signaler visuellement cette première ouverture.The invention relates to a screw cap comprising a tamper-evident ring that breaks when the container is first opened on which the cap is mounted to visually indicate this first opening.

De tels bouchons sont de plus en plus utilisés, aussi bien sur les récipients contenant des produits alimentaires que sur ceux contenant des produits pharmaceutiques, et, cela, sur des récipients en verre ou en matière synthétique.Such caps are used more and more, both on containers containing food products and on those containing pharmaceutical products, and, this, on glass or plastic containers.

Dans les bouchons actuels de ce type, la bague d'inviolabilité est liée au bouchon par des pontets de matière qui se rompent lorsque, sous l'action du dévissage du bouchon, une collerette interne de cette bague d'inviolabilité vient en appui sous une bague du col du récipient. Après extraction totale du bouchon, la bague d'inviolabilité reste autour du col du récipient et cela d'autant plus qu'elle est circulaire et que sa collerette interne, favorisant sa rupture, a un diamètre inférieur à celui de la bague du col, ce qui empêche de l'extraire sans effort ou sans sectionnement.In current caps of this type, the tamper-evident ring is linked to the cap by bridges of material which break when, under the action of unscrewing the cap, an internal flange of this tamper-evident ring comes to bear under a container neck ring. After total extraction of the stopper, the tamper-evident ring remains around the neck of the container, all the more so since it is circular and its internal collar, promoting its rupture, has a diameter less than that of the neck ring, which prevents it from being extracted effortlessly or without sectioning.

Si la conservation de la bague d'inviolabilité sur le col du récipient ne pose pas de problème pour les récipients jetables, il n'en est pas de même pour les récipients réutilisables car, avant leur passage sur une chaîne de conditionnement assurant leur remplissage et leur bouchage avec un nouveau bouchon, il est nécessaire d'ôter la bague d'inviolabilité de l'ancien bouchon. Cette opération ne peut pas être effectuée manuellement de manière rentable et nécessite donc des moyens techniques spéciaux augmentant le coût de la chaîne de conditionnement.If the conservation of the tamper-evident ring on the neck of the container does not pose a problem for disposable containers, it is not the same for reusable containers because, before their passage on a packaging line ensuring their filling and their closure with a new cap, it is necessary to remove the tamper-evident ring from the old cap. This operation cannot be carried out manually in a profitable manner and therefore requires special technical means increasing the cost of the packaging line.

En outre, il est de plus en plus fréquent de recycler les récipients en matière synthétique. Or, si la bague d'inviolabilité, généralement réalisée en un matériau différent de celui constituant le récipient, demeure sur le col de celui-ci lors de la première ouverture du bouchon, il convient ensuite de la retirer avant de procéder au réglage du récipient.In addition, it is more and more common to recycle plastic containers. However, if the tamper-evident ring, generally made of a material different from that constituting the container, remains on the neck thereof when the cap is opened for the first time, it should then be removed before adjusting the container. .

La présente invention a pour but de remédier à ces inconvénients en fournissant un bouchon à vis à bague d'inviolabilité dans lequel la bague reste liée au bouchon après la première ouverture, c'est à dire à un bouchon supprimant les problèmes posés par la présence de la bague sur le récipient lors du reconditionnement de ce dernier.The object of the present invention is to remedy these drawbacks by providing a screw cap with a tamper-evident ring in which the ring remains linked to the cap after the first opening, that is to say to a cap eliminating the problems posed by the presence of the ring on the container during reconditioning of the latter.

A cet effet, dans le bouchon selon l'invention, la bague d'inviolabilité est composée d'au moins deux fragments semi-circulaires séparés par au moins une fente longitudinale et liés chacun au bouchon, d'une part, par un pontet non sécable, et d'autre part, par des pontets sécables agencés pour provoquer le début de la rupture au milieu de l'intervalle entre le pontet non sécable et l'extrémité du fragment qui estjuxtaposée à la fente.To this end, in the stopper according to the invention, the tamper-evident ring is composed of at least two semi-circular fragments separated by at least one longitudinal slot and each linked to the stopper, on the one hand, by a non-trigger guard. breakable, and secondly, by breakable bridges arranged to cause the beginning of the rupture in the middle of the interval between the non-breakable trigger guard and the end of the fragment which is juxtaposed with the slit.

Grâce à cet agencement, le bouchon selon l'invention est mis en place sur le col du récipient comme les bouchons actuels. Lors de la première ouverture, chacun de ses fragments de bague est d'abord sectionné au milieu de sa longueur puis, progressivement, jusqu'à son extrémité libre qui cède franchement en visualisant cette première ouverture et en tolérant le dévissage total du bouchon. En raison du pontet non sécable reliant chaque fragment au bouchon, les fragments de bague font corps avec le bouchon et ne restent donc pas sur le col du récipient. Enfin, les fragments de la bague d'inviolabilité qui restent adhérents au bouchon n'empêchent pas son revissage sur le récipient et sont, du fait de cette liaison, plus facilement éliminés en cas de réutilisation du récipient, puisqu'ils en sont ôtés en même temps que le bouchon.Thanks to this arrangement, the cap according to the invention is placed on the neck of the container like the current caps. During the first opening, each of its ring fragments is first sectioned in the middle of its length and then, gradually, until its free end which gives way frankly by visualizing this first opening and tolerating the total unscrewing of the cap. Because of the non-breakable trigger guard connecting each fragment to the stopper, the ring fragments become one with the stopper and therefore do not remain on the neck of the container. Finally, the fragments of the tamper-evident ring which remain adherent to the stopper do not prevent it from being screwed back onto the container and are, because of this connection, more easily eliminated in the event of re-use of the container, since they are removed therefrom. same time as the cap.

Aux figures 1 à 8, la référence 2 désigne un bouchon à vis réalisé en matière synthétique notamment en polyéthylène, 3 une bague d'inviolabilité liée à une bague de fixation 4 s'encliquetant élastiquement sur une nervure 5 saillant à l'intérieur de la jupe 2a du bouchon. La référence 6 désigne une collerette discontinue, saillant à l'intérieur de la bague d'inviolabilité 3 et apte, de façon connue, à venir buter dans la phase de première ouverture du bouchon sur la face inférieure de la bague 7 du col 8 du récipient. Cette collerette 6 est évasée vers le bas de manière à pouvoir se déformer radialement et élastiquement lors de son introduction sur le filetage et sur la bague 7 du col du récipient, après que le bouchon 2 ait été associé à la bague d'inviolabilité 3-4.In FIGS. 1 to 8, the reference 2 designates a screw cap made of synthetic material, in particular polyethylene, 3 a tamper-evident ring linked to a fixing ring 4 snapping elastically onto a rib 5 projecting inside the skirt 2a of the plug. The reference 6 designates a discontinuous flange, protruding inside the tamper-evident ring 3 and suitable, in known manner, to come up against the phase of first opening of the stopper on the underside of the ring 7 of the neck 8 of the container. This flange 6 is flared downward so as to be able to deform radially and elastically when it is introduced onto the thread and onto the ring 7 of the neck of the container, after the cap 2 has been associated with the tamper-evident ring 3- 4.

Selon l'invention, et comme le montre la figure 3, la bague d'inviolabilité 3 est composée de deux fragments semi-circulaires 3a-3b qui sont séparés l'un de l'autre par une fente verticale 10. Dans la forme d'exécution représentée aux figures 1 à 8, les fragments 3a et 3b sont reliés à la bague de fixation 4, d'une part, par des pontets sécables 12 et, d'autre part, un pontet non sécable 13 commun aux deux fragments et diamétralement opposé à l'ouverture 10. Sur chacun des fragments 3a ou 3b, les pontets sécables 12 sont séparés par des pas différents P1-P2 et P3 qui vont en décroissant depuis le milieu du fragment jusqu'à ses extrémités. L'extrémité libre du fragment est liée à la bague 4 par les pontets 12a ayant le pas P3 le plus petit.According to the invention, and as shown in FIG. 3, the tamper-evident ring 3 is composed of two semi-circular fragments 3a-3b which are separated from each other by a vertical slot 10. In the form of 'execution shown in Figures 1 to 8, the fragments 3a and 3b are connected to the fixing ring 4, on the one hand, by breakable bridges 12 and, on the other hand, a non-breakable bridge 13 common to the two fragments and diametrically opposite to the opening 10. On each of the fragments 3a or 3b, the breakable bridges 12 are separated by different steps P1-P2 and P3 which decrease from the middle of the fragment to its ends. The free end of the fragment is linked to the ring 4 by the bridges 12a having the smallest pitch P3.

Lorsque le bouchon est associé à la bague d'inviolabilité selon l'invention, il est monté sur le col du récipient comme les bouchons traditionnels à bague d'inviolabilité circulaire sans solution de continuité. Ils se présentent alors sous la forme représentés à la figure 4.When the stopper is associated with the tamper-evident ring according to the invention, it is mounted on the neck of the container like traditional stoppers with a circular tamper-evident ring without any solution of continuity. They then take the form shown in FIG. 4.

Lors de la première ouverture du récipient, et grâce à la collerette 6 venant prendre appui sous la bague 7 du col 8 du récipient, mais aussi grâce à la différence de répartition des pontets sécables 12, chacun des fragments de bagues d'inviolabilité cède d'abord dans la partie la moins résistante, c'est à dire au milieu de sa longueur, comme montré à la figure 5.When the container is opened for the first time, and thanks to the flange 6 which comes to bear under the ring 7 of the neck 8 of the container, but also thanks to the difference in distribution of the breakable bridges 12, each of the fragments of tamper-evident rings gives way to 'first in the weakest part, i.e. in the middle of its length, as shown in Figure 5.

En continuant l'opération de dévissage dans le sens de la flèche 14 de figure 6, l'opérateur exerce sur les pontets 12 non cassés un effort de plus en plus important qui provoque le sectionnement progressif des pontets disposés de part et d'autre de la zone ayant déjà cédée, et cela jusqu'au moment où cèdent à leur tour les pontets 12a disposés à l'extrémité libre du fragment correspondant de la bague d'inviolabilité, c'est à dire les pontets disposés à proximité de la fente 10.By continuing the unscrewing operation in the direction of the arrow 14 in FIG. 6, the operator exerts on the non-broken bridges 12 an increasing force which causes the gradual sectioning of the bridges arranged on either side of the zone having already given way, and this until the moment when the bridges 12a disposed in their turn end at the free end of the corresponding fragment of the tamper-evident ring, that is to say the bridges arranged near the slot 10 .

A la fin du mouvement de fractionnement de la bague d'inviolabilité, comme le montre la figure 8, les fragments de celle-ci sont reliés par l'une de leurs extrémités et par le pontet sécable 13 à la bague 4, donc au bouchon 2. Ils présentent deux extrémités libres qui sont écartées et pendent sous le bouchon en mettant en évidence cette première ouverture, sans pour autant s'opposer au revissage du bouchon sur le col du récipient, comme montré à la figure 7.At the end of the fractionation movement of the tamper-evident ring, as shown in FIG. 8, the fragments of the latter are connected by one of their ends and by the breakable bridge 13 to the ring 4, therefore to the stopper 2. They have two free ends which are spaced apart and hang under the stopper, highlighting this first opening, without however opposing the screwing of the stopper on the neck of the container, as shown in FIG. 7.

Grâce à cet agencement, le sectionnement de chacun des fragments de la bague d'inviolabilité s'effectue de manière contrôlée et orientée, en produisant un effort résistant qui va en croissant, en même temps que croît l'effort d'écartement engendré, dans un sens, par le dévissage du bouchon et, dans l'autre, par l'appui de la collerette 6 sur la bague 7 du récipient.Thanks to this arrangement, the sectioning of each of the fragments of the tamper-evident ring is carried out in a controlled and oriented manner, producing a resistant force which increases, at the same time as the separation force generated increases. one direction, by unscrewing the cap and, in the other, by pressing the flange 6 on the ring 7 of the container.

Grâce à cet agencement, pour réutiliser le récipient, il suffit de retirer le bouchon, ce qui est une opération beaucoup plus facile à réaliser que'celle consistant à retirer de son col une bague annulaire calée par la bague 7 du récipient.Thanks to this arrangement, to reuse the container, it suffices to remove the stopper, which is a much easier operation than that of removing from its neck an annular ring wedged by the ring 7 of the container.

La bague d'inviolabilité qui a été décrite dans le cas de son application à un bouchon à deux composants peut bien entendu être reliée directement à la jupe 2a de ce bouchon, pourvu que cette liaison s'effectue au moyen des pontets 12 et 13 décrits ci-dessus.The tamper-evident ring which has been described in the case of its application to a two-component stopper can of course be connected directly to the skirt 2a of this stopper, provided that this connection is made by means of the bridges 12 and 13 described above.

Par ailleurs, l'aménagement d'une zone de rupture privilégiée sur chacun des fragments de la bague d'inviolabilité, aménagement qui, dans la forme d'exécution ci-dessus décrite, résulte d'une répartition particulière des pontets 12, peut aussi provenir d'une modification de la section transversale de ces pontets, section allant alors en croissant depuis le milieu du fragment de bague jusqu'à ses extrémités, mais aussi par la combinaison de ces deux techniques.Furthermore, the arrangement of a privileged rupture zone on each of the fragments of the tamper-evident ring, arrangement which, in the embodiment described above, results from a particular distribution of the bridges 12, can also come from a modification of the cross section of these bridges, section then increasing from the middle of the ring fragment to its ends, but also by the combination of these two techniques.

Quant à la bague d'inviolabilité, elle peut être aussi composée, comme montré à la figure 9, par deux demi-bagues 20a et 20b liées, chacune, à la bague de fixation 4 ou au bouchon 2 par un pontet non sécable 22 disposé en leur milieu et divisant, chacune d'elles, en deux fragments 21a-21b et 21c-21d. L'extrémité libre de chaque fragment est séparée de l'extrémité du fragment contiguë de l'autre demi-bague par une fente 23 et chaque fragment est lui-même relié à la bague 4, ou directement au bouchon 2, par des pontets sécables 24 dont la répartition et/ou la section transversale sont déterminées pour former une zone de rupture préférentielle au milieu de la longueur dudit segment.As for the tamper-evident ring, it can also be composed, as shown in FIG. 9, by two half-rings 20a and 20b each linked to the fixing ring 4 or to the plug 2 by a non-breakable bridge 22 arranged in the middle and dividing each of them into two fragments 21a-21b and 21c-21d. The free end of each fragment is separated from the end of the contiguous fragment of the other half-ring by a slot 23 and each fragment is itself connected to the ring 4, or directly to the plug 2, by breakable bridges 24, the distribution and / or cross section of which are determined to form a preferential rupture zone in the middle of the length of said segment.

Dans la forme d'exécution représentée à la figure 10, la bague d'inviolabilité est composée de deux fragments indépendants 26a-26b dont l'extrémité amont, par rapport au sens de dévissage du bouchon représenté par la flèche 27 à la figure 10, est reliée au bouchon 2, ou à la bague 4, par un pontet non sécable 28, et dont l'extrémité libre est séparée du pontet de l'autre fragment par une fente verticale 29. Chacun de ces fragments 26a-26b est relié au bouchon 2, ou à la bague 4, par des pontets sécables 30 dont la réparition et/ou la section transversale sont déterminées pour fournir une zone de rupture préférentielle au milieu de leur longueur.In the embodiment shown in FIG. 10, the tamper-evident ring is composed of two independent fragments 26a-26b, the upstream end of which, relative to the direction of unscrewing of the stopper represented by arrow 27 in FIG. 10, is connected to the plug 2, or to the ring 4, by a non-breakable trigger guard 28, and the free end of which is separated from the trigger guard of the other fragment by a vertical slot 29. Each of these fragments 26a-26b is connected to the plug 2, or to ring 4, by breakable bridges 30, the distribution of which and / or the cross section are determined to provide a preferential rupture zone in the middle of their length.

Il ressort de ce qui précède que, quelle que soit la forme d'exécution des languettes et leurs moyens de liaison au bouchon 2, ou à la bague de fixation 4, toutes les bagues d'inviolabilité qui ont été décrites ci-dessus ont en commun l'aménagement de zones de rupture préférentielle situées à mi-distance entre l'extrémité libre de chaque fragment et le point de liaison permanent de ce fragment avec le bouchon 2 ou la bague 4.It follows from the above that, whatever the embodiment of the tongues and their means of connection to the plug 2, or to the fixing ring 4, all the tamper-evident rings which have been described above have in common the arrangement of preferential rupture zones located midway between the free end of each fragment and the permanent connection point of this fragment with the plug 2 or the ring 4.
